Fig. 1A-1K illustrate an exemplary embodiment of a vacuum tool 100, the vacuum tool 100 being operable to separate metal from other debris during vacuum operation, thereby allowing easy removal of the metal and preventing damage to the hose and other components of the cleaner.

The embodiment of the vacuum tool 100 shown in fig. 1A-1H includes a body 104, the body 104 having a first end 104a, a second end 104b opposite the first end 104a, and a longitudinal axis 108 extending between the first end 104a and the second end 104 b. The body 104 also includes a base portion 112, an intermediate portion 116, and a connecting portion 120. The base portion 112 is located near the first end 104a, the connecting portion 120 is located near the second end 104b, and the intermediate portion 116 is located between the base portion 112 and the connecting portion 120. In the exemplary embodiment, base portion 112 is integrally formed with intermediate portion 116, and intermediate portion 116 is integrally formed with connecting portion 120. In other embodiments, the base portion 112, the intermediate portion 116, and the connecting portion 120 may be formed as separate pieces that are assembled together as a single unit. The tool 100 also includes an opening 124 in the base 112 that extends through the body 104 from the first end 104a to the second end 104 b.

The base 112 and the opening 124 define an inlet 128 for collecting dust and debris. In the exemplary embodiment, base 112 is substantially rectangular and includes a main wall 132 and four

side walls

136a, 136b, 136c, 136d extending from main wall 132. The shape of the base 112 can also have a variety of other different configurations. Specifically, in the illustrated embodiment, the base 112 includes a first sidewall 136a, a second sidewall 136b, a third sidewall 136c, and a fourth sidewall 136 d. The first sidewall 136a is positioned opposite the second sidewall 136b such that the first sidewall 136a and the second sidewall 136b are oriented parallel with respect to each other. The third and

fourth sidewalls

136c and 136d are located between the first and second sidewalls 136a and 136 b. Third sidewall 136c is positioned opposite fourth sidewall 136d such that third sidewall 136c and fourth sidewall 136d are oriented parallel with respect to each other. In some embodiments, the distal ends of some of all of the sidewalls 136a, 136b, 136c, 136d may include teeth and/or bristles configured to scrub the work surface.

The base 112 includes a first ledge 140a coupled to the first sidewall 136a and a second ledge 140b coupled to the second sidewall 136 b. Ledges 140a, 140b extend along the first and second sidewalls 136a, 136b and project outwardly from the first and second sidewalls 136a, 136 b. With continued reference to fig. 1A-1H, a first magnet 144a is coupled to the first ledge 140a and a second magnet 144b is coupled to the second ledge 140 b. The

magnets

144a, 144b in the illustrated embodiment are generally rectangular elongated strips positioned along the outer edges of the

ledges

140a, 140 b. In some embodiments, the

magnets

144a, 144b can have other different shapes and sizes, and the base 112 can include fewer or more magnets. In other embodiments, the

magnets

144a, 144b may be positioned on any surface of the base 112 (e.g., on the third and

fourth sidewalls

136c, 136 d). In the illustrated embodiment, the

magnets

144a, 144b are positioned on a portion of the base 112 adjacent the periphery of the inlet 128. In some embodiments, the

magnets

144a, 144b may be positioned on other portions of the body 104.

The middle portion 116 includes a first wall 148a, a second wall 148b opposite the first wall 148a, a third wall 148c, and a fourth wall 148d opposite the third wall 148 c. Third and

fourth walls

148c, 148d extend between the first and

second walls

148a, 148 b. In the illustrated embodiment, the first sidewall 136a of the base 112 is coplanar and integrally formed with the first wall 148a of the middle portion 116. In other embodiments, the first side wall 136a of the base 112 and the first wall 148a of the middle portion 116 may be positioned in different configurations relative to each other and, as described above, may be formed and assembled as separate components.

In some embodiments (fig. 1F-1H), the middle portion 116 includes one continuous curved wall, rather than four differently configured walls. Specifically, the intermediate portion 116 is formed by a first curved wall portion 152 flowing into a second curved wall portion 154. In the illustrated embodiment, the first curved wall portion 152 is integrally formed with the connecting portion 120, while the second curved wall portion 154 is integrally formed with the base portion 112. The first curved wall portion 152 includes a first end 152a positioned adjacent the connecting portion 120 and a second end 152b positioned adjacent the second curved wall 154. Similarly, the second curved wall 154 includes a first end 154a positioned adjacent the second end 152b of the first curved wall 152 and a second end 154b positioned adjacent the base 112 (fig. 1H). The

curved walls

152, 154 are tapered cylindrical walls. That is, the diameter of the first curved wall 152 increases from the first end 152a to the second end 152b, and the diameter of the second curved wall 154 increases from the first end 154a to the second end 154 b.

Referring to fig. 1A-1H, the connecting portion 120 is integrally formed with or otherwise coupled to the second end 104b of the body 104 and extends from the second end 104b of the body 104. For example, in some embodiments, the connection 120 may be rotatably coupled to the second end 104b of the body 104 by a rotary joint (sweivej). The connection 120 includes a conduit 156 defining an outlet 160 in fluid communication with the opening 124. The outlet 160 is in fluid communication with a wand or hose of the vacuum cleaner. In the illustrated embodiment, the opening 124 tapers in a direction from the inlet 128 to the outlet 160 to convey dust and debris from the inlet 128 to the outlet 160. That is, the diameter of the opening 124 decreases from the inlet 128 to the outlet 160. In other embodiments, the opening 124 may be substantially constant. In the illustrated embodiment, the connection 120 is substantially parallel to the longitudinal axis 108. However, in alternative embodiments, the connection 120 may be angled relative to the longitudinal axis 108.

With continued reference to fig. 1A-1E, the connection 120 may include a universal coupler 164 extending from the conduit 156 and configured to couple to vacuum hoses and rods having different diameters. In some embodiments, the universal coupler provides channels having different diameters to receive and couple different sized hoses and rods. In the embodiment of fig. 1D and 1E, the universal coupler 164 includes a first cylindrical wall 166, a second cylindrical wall 168, and a channel 172 formed therebetween. Second cylindrical wall 168 surrounds first cylindrical wall 166 such that the diameter of second cylindrical wall 168 is greater than the diameter of first cylindrical wall 166 to space the two walls apart and form a channel 172 therebetween. The first cylindrical wall 166 tapers in a direction from the intermediate portion 116 toward the second end 104b of the body 104.

Referring to fig. 1D and 1E, the first cylindrical wall 166 includes a first shoulder 176 and a second shoulder 180 formed on an outer surface of the first cylindrical wall 166. First and

second shoulders

176 and 180 divide passage 172 into first, second, and

third portions

190a, 190b, 190c such that each portion 190a-190c has a different diameter. Accordingly, hoses or rods having different diameters may be coupled to the first cylindrical wall 166 within one of the portions 190a-190c of the channel 172 to secure the hose or rod to the wall 166 in the channel 172. In some embodiments, the first cylindrical wall 166 may include fewer or more shoulders. In further embodiments, the second cylindrical wall 168 may be tapered, or both the first and second

cylindrical walls

166, 168 may be tapered.

As an alternative to or in addition to the channel 172, with continued reference to fig. 1D and 1E, the conduit 156 may taper in a direction from the second end 104b of the body 104 toward the intermediate portion 116. The inner surface of the conduit 156 includes a third shoulder 182 and a fourth shoulder 184 that extend into the opening 124. Third and

fourth shoulders

182 and 184 divide conduit 156 into fourth, fifth, and

sixth portions

186a, 186b, 186c such that each portion 186a-186c has a different diameter. Further, the fourth, fifth and

sixth portions

186a, 186b, 186c have different diameters than the first, second and

third portions

190a, 190b, 190 c. Accordingly, hoses or rods having different diameters may be received within one of the portions 186a-186c within the conduit 156 to couple the hose and/or rod to the connection 120. In some embodiments, the conduit 156 may include fewer or more shoulders.

In the illustrated embodiment, the universal coupler 164 is integrally formed with the connection portion 120 and the conduit 156. In other embodiments, the universal coupler 164 may be coupled to the conduit 156 in other manners, such as by a rotary joint. In some embodiments, such as in fig. 1F-1H, the connection 120 may include different coupling configurations.

In some embodiments, the base 112 of the tool 100 has a width (measured between the first sidewall 136a and the second sidewall 136b of the base 112) of about 7-10 inches. In the embodiment shown, the width is about 178 mm. In alternative embodiments, the tool 100 may have a smaller or larger width. Additionally, the tool 100 has a height (measured between the first end 104a of the body 104 and the second end 104b of the body 104) of about 170 mm. In alternative embodiments, the tool 100 may have a smaller or larger height.

In operation, suction generated by the vacuum cleaner and applied through the connection 120 draws dust and debris from the work surface into the inlet 128. The

magnets

144a, 144b positioned at opposite peripheries of the inlet 128 attract and retain metal debris picked up from the work surface before the inlet 128 passes over the metal debris so that the metal debris is not drawn into the inlet 128. Thus, metal debris present on the work surface is not drawn into the inlet by the suction generated by the vacuum cleaner, which could otherwise damage the vacuum cleaner or its hose.

1I-1K illustrate another embodiment of a tool 100', where similar components are indicated with prime notation. The tool 100' is substantially identical to the tool 100, with a different base configuration.

As shown in fig. 1I-1K, the tool 100' includes a base 112' coupled to a connecting portion 120 '. The base 112' includes a first wall 188a ', a first side wall 192a ', and a second side wall 192b ' that are angled with respect to the second wall 188b '. The first wall 188a 'and the second wall 188b' are angled with respect to each other.

The base 112 'also includes a rotating member or rod 194'. Member 194' rotates and locks in the up (removal) position and the down (deployed use) position. More specifically, member 194 'is movably (e.g., pivotably) coupled to base 112'. Member 194 'includes an elongated portion 196' extending between a first coupling portion 198a 'and a second coupling portion 198 b'. The first and second coupling portions 198a ', 198b' are movably (e.g., pivotably) coupled (e.g., by fasteners, etc.) to the first and second side walls 192a ', 192b', respectively. In the embodiment shown in fig. 1J, first coupling portion 198a 'and second coupling portion 198b' are coupled to sidewalls 192a ', 192b' by first pin 170a 'and second pin 170 b'. The first and second pins 170a 'and 170a' are located between the first and second sidewalls 192a 'and 192 b'. The first pin 170a 'extends through the first sidewall 192a' and the second pin 170b 'extends through the second sidewall 192 b'. The pins 170a ', 170b' define an axis 174 'that is parallel to the longitudinal axis of the tool 100'. The first coupling portion 198a ' and the second coupling portion 198b ' are pivotable about the axis 174 '.

One or more magnets 144a 'are coupled to the member 194' and are configured to selectively engage or otherwise be positioned adjacent a work surface. The magnet 144a 'is located on a first surface of the member 194'. The plane defined by the first surface may be positioned at a desired angle relative to the longitudinal axis of the coupling portions 198a ', 198 b'. Member 194 'is movable (e.g., pivotable) about axis 174' between a first stowed position in which magnet 144a 'is spaced from the work surface and a second use or deployed position in which magnet 144a' engages or is otherwise positioned adjacent the work surface. The plane defined by the first surface may be positioned at a desired angle (e.g., an oblique angle) relative to the longitudinal axis of the coupling portions 198a ', 198b', such that the plane of the first surface is also angled relative to the plane defined by the working surface in the use position. In some embodiments, in the use position, the plane defined by the first surface may be positioned parallel to the longitudinal axis of the coupling portions 198a ', 198b', and thus also parallel to the working surface. In some embodiments, there may be fewer or more magnets coupled to the first surface of the elongated portion 196'. In other embodiments, all or a portion of member 194' may be magnetized in any suitable manner.

Fig. 2A-2D illustrate a vacuum tool 200 according to another embodiment that includes bristles to facilitate scrubbing of various types of surfaces.

The exemplary embodiment of the vacuum tool 200 shown in fig. 2A-2E includes a body 204, the body 204 having a first end 204a, a second end 204b opposite the first end 204a, and a longitudinal axis 208 (fig. 2C) extending between the first end 204a and the second end 204 b. The body 204 also includes a head portion 212, an intermediate portion 216, and a connecting portion 220. The head portion 212 is located near the first end 204a, the connecting portion 220 is located near the second end 204b, and the intermediate portion 216 is located between the head portion 212 and the connecting portion 220. In the illustrated embodiment, the head portion 212 is integrally formed with the intermediate portion 216, and the intermediate portion 216 is integrally formed with the connecting portion 220. In other embodiments, the head portion 212, the intermediate portion 216, and the connecting portion 220 may be formed as separate pieces that are assembled together as a single unit. The tool 200 also includes an opening 224 extending through the body 204 from the first end 204a to the second end 204 b. At least a portion of the opening 224 is parallel to the longitudinal axis 208.

The head 212 and the opening 224 define an inlet 228 for collecting dust and debris. The head 212 includes a top wall 232, a bottom wall 236, a first sidewall 240a, a second sidewall 240b, a first tapered sidewall 244a, and a second tapered sidewall 244 b. The top wall 232 is positioned opposite the bottom wall 236 such that the top wall 232 and the bottom wall 236 are oriented parallel with respect to each other. Similarly, the first sidewall 240a is positioned opposite the second sidewall 240b such that the first sidewall 240a and the second sidewall 240b are oriented parallel with respect to each other. The first and second tapered sidewalls 244a, 244b are tapered such that the width of the opening 224 extending through the head 212 decreases from the first end 204a of the body 204 (e.g., adjacent the inlet 228) toward the second end 204b of the body 204 to convey dust and debris drawn into the inlet 228 to the intermediate portion 216.

The head 212 also includes first and second apertures 248a, 248B (fig. 2D) extending through the first sidewall 240a, and third and fourth apertures 248c, 248D (fig. 2A-2B, 2D) extending through the second sidewall 240B. In the illustrated embodiment, the apertures 248a-248d are generally cylindrical. However, in alternative embodiments, the apertures 248a-248d may be formed in alternative shapes and sizes. Referring to fig. 2D, the first sidewall 240a includes a first groove 252a and a second groove 252b formed in an inner surface of the first sidewall 240 a. A first recess 252a extends from the first aperture 248a to the outer end of the first sidewall 240a, and a second recess 252b extends from the second aperture 248b to the outer end of the first sidewall 240 a. Similarly, the second sidewall 240b includes a third recess 252c and a fourth recess 252d formed in the inner surface of the second sidewall 240 b. A third recess 252c extends from the third aperture 248c to the outer end of the second sidewall 240b and a fourth recess 252d extends from the fourth aperture 248d to the outer end of the second sidewall 240 b.

With continued reference to fig. 2D, the tool 200 includes a brush member 256 removably coupled to the head 212. The brush member 256 is selectively positionable in a first position and a second position within the head 212. Member 256 includes an elongated support portion 260 extending between a first coupling portion 264a and a second coupling portion 264 b. A series of several bristles 268 are coupled to the elongate support 260 and are configured to selectively engage or otherwise be positioned adjacent a work surface during use. The bristles 268 extend outwardly away from the first surface of the elongated support 260. Bristles 268 positioned on member 256 are configured to loosen dirt and debris from the work surface to help clean the work surface and/or protect the work surface from damage. The positioning of the brush member 256 within the head 212 allows air to flow over and/or under the bristles 268 during use. More specifically, the positioning of the component 256 within the head 212 allows air to flow within a first space 266a between the upper side 256a of the brush member 256 and the top wall 232 and within a second space 266b between the lower side 256b of the brush member 256 and the bottom wall 236. In other embodiments, the brush member 256 may be disposed at other locations within the head 212. Further, in some embodiments, the bristles 268 may be oriented in different patterns and/or configurations. In some embodiments, the brush member 256 may additionally or alternatively include a squeegee or cushion (rather than bristles 268) extending along the elongated support 260. In some embodiments, a skirt (e.g., a rubber skirt) may be provided around the periphery of the opening 224 of the head 212 to form a seal against the work surface as the work surface is scrubbed with the brush member 256.

The first and

second coupling parts

264a and 264b are detachably coupled to the first and

second side walls

240a and 240b, respectively. Specifically, the first and

second coupling portions

264a, 264b are shaped and sized to fit within the apertures 248a-248d formed in the

sidewalls

240a, 240 b. To position brush member 256 in the first position within head 212, first and

second coupling portions

264a, 264b slide along first and

third recesses

252a, 252c and engage first and

third apertures

248a, 248c, respectively. Alternatively, to position the brush member 256 in the second position within the head 212, the first and

second coupling portions

264a, 264b slide along the second and

fourth recesses

252b, 252d and engage the second and

fourth apertures

248b, 248d, respectively. When the brush member 256 is in the first position, the brush member 256 extends along a first axis 270 that is perpendicular to the longitudinal axis 208. When the brush member 256 is in the second position, the brush member 256 extends along a second axis 274, the second axis 274 being offset from the first axis 270 and parallel to the first axis 270. The user may selectively position the brush member 256 in the first position or the second position depending on the position of the debris relative to the head 212. In some embodiments, the first and

second coupling portions

264a and 264b are coupled to the first and second sidewalls 240a and 240b by fasteners or the like. In some embodiments, the elongate portion 260 of the brush member 256 is rotatable about a first axis 270 and a second axis 274 during operation.

Referring to the embodiment shown in fig. 2A-2B, the intermediate portion 216 is a generally rectangular tube. In the illustrated embodiment, the intermediate portion 216 includes two sets of opposing, parallel, elongated grooves 272 formed in and extending partially around the outer surface of the intermediate portion 216. In other embodiments, the intermediate portion 216 may be formed from other shapes and may be tapered.

With further reference to the embodiment shown in fig. 2A-2C, the connecting portion 220 may be integrally formed with the second end 204b of the body 204 or otherwise coupled to the second end 204b of the body 204. The outer surface of the connecting portion 220 defines a gripping surface that facilitates gripping by a user during operation. Coupling portion 220 includes a conduit 276 (fig. 2C) that defines an outlet 280 in fluid communication with opening 224. When connected to a wand or hose of a vacuum cleaner, the outlet 280 is in fluid communication with the internal conduit of the wand or hose. The conduit 276 includes a cylindrical portion 284 and a tapered portion 288 (fig. 2A, 2C). The tapered portion 288 is located between the intermediate portion 216 and the cylindrical portion 284. The tapered portion 288 tapers in a direction from the inlet 228 to the outlet 280. That is, the width of the portion 288 decreases in a direction from the intermediate portion 216 to the connecting portion 220. In other embodiments, the entire connecting portion 220 is cylindrical. Referring to fig. 2C, the connecting portion 220 extends along an axis 292 oriented obliquely with respect to the longitudinal axis 208. Thus, when the tool 200 is positioned against a work surface, the head portion 212 and the intermediate portion 216 are positioned at an angle relative to the connecting portion 220. More specifically, when the user uses tool 200, axis 292 is oriented substantially parallel to the work surface, at an angle to head portion 212 and intermediate portion 216. Thus, a user may comfortably grasp the tool 200 while suctioning dust and debris in hard-to-reach locations. Further, the orientation of the connection 220 allows the user to apply a greater force or effect to the tool against the work surface during use.

Referring to fig. 2A-2C, the connection 220 additionally includes a universal coupler 296, the universal coupler 296 extending from the conduit 276 and configured to couple to vacuum hoses and rods having different sizes. The universal coupler 296 is substantially the same as the universal coupler 164 described above with respect to fig. 1A-1D. Reference is made herein to the above description of the universal coupler 164. In some embodiments, the connection 220 may include other configurations.

In some embodiments, the base 212 of the tool 200 has a width (measured between the first and second sidewalls of the head) of about 100.7 mm. In alternative embodiments, the tool 200 may have a smaller or larger width. Additionally, the tool 200 has a length (measured between the first end 204a of the body 204 and the second end 204b of the body 204) of about 384.2 mm. In alternative embodiments, the tool 200 may have a smaller or larger height.

In operation, the vacuum cleaner generates suction through the connection 220 and draws dust and debris from the work surface into the inlet 228 and carries the dust and debris by the airflow to the outlet 280. The user may grasp the gripping surface of the tool 200 to position the bristles 268 against the work surface. In this orientation, the connecting portion 220 extends generally parallel to the working surface, and the head portion 212 and the intermediate portion 216 are positioned at an oblique angle relative to the working surface. This angled orientation allows the user to exert a greater force or action on the tool 200 (and bristles 268) against the work surface. Scrubbing the work surface with the bristles 268 will loosen dirt and debris caught on the work surface and help clean the surface while also protecting the surface from damage. Due to the orientation of the bristles 268 within the head 212, air flows over and under the brush member 256 to remove dirt and debris from the working surface throughout the cleaning operation. The relatively narrow height of the head 212 allows a user to position the tool 200 in an area that is difficult to access (e.g., under furniture).

Fig. 3A-3E illustrate an embodiment of a vacuum tool 300 shaped and dimensioned to effectively clean corner regions of a work surface.

The embodiment of the vacuum tool 300 shown in fig. 3A-3E includes a body 304 having a first end 304a, a second end 304b opposite the first end 304a, and a longitudinal axis 308 (fig. 3C) extending between the first end 304a and the second end 304 b. The body 304 also includes a head portion 312, an intermediate portion 316, and a connecting portion 320. The head portion 312 is located near the first end 304a, the connecting portion 320 is located near the second end 304b, and the intermediate portion 316 is located between the head portion 312 and the connecting portion 320. With reference to the embodiment shown in fig. 3A-3D, head portion 312 is removably coupled to intermediate portion 316, and intermediate portion 316 is removably coupled to connecting portion 320. The tool 300 also includes an opening 324 extending through the body 304 from the first end 304a to the second end 304 b. At least a portion of the opening 324 is parallel to the longitudinal axis 308. In some embodiments, such as in fig. 3E, the tool 300 is formed as a unitary piece. More specifically, the head portion 312 is integrally formed with the intermediate portion 316, and the intermediate portion 316 is integrally formed with the connecting portion 320.

The head 312 and the opening 324 define an inlet 328 for collecting dust and debris. The head 312 includes a head 332 and a connector 336. The head 332 is shaped to fit within the corner region of the working surface. Specifically, the head 332 is generally teardrop-shaped such that the head 332 is generally cylindrical and includes a somewhat pointed edge 340. The periphery of the outer surface of the head 332 includes a series of apertures shaped and dimensioned to receive bristles 344. Bristles 344 extend away from the bottom surface and are configured to selectively engage or otherwise be positioned adjacent the working surface. The bristles 344 located on the sharp edge 340 of the head 332 extend in an outward direction to allow access to corners and tight spaces.

The connector 336 is generally conical and cylindrical. Connector 336 includes a first end 336a adjacent head 332 and a second end 336b opposite first end 336 a. The connector 336 tapers in a direction from the second end 336b to the first end 336a of the connector 336. That is, the diameter of the portion of the opening 324 within the connector 336 decreases from the second end 336b to the first end 336 a. In some embodiments (fig. 3E), the connector 336 is cylindrical and the portion of the opening 324 extending through the connector 336 has a constant diameter. In the disclosed embodiment, a first end 336a of the connector 336 is integrally formed with the head 332, and a second end 336b of the connector 336 is removably coupled to the intermediate portion 316. More specifically, the second end 336b of the connector includes external threads 348. Other embodiments may include a differently shaped connector 336.

Referring to fig. 3A, 3B, and 3D, the intermediate portion 316 is generally cylindrical and includes a first end 316a and a second end 316B opposite the first end 316 a. The first end 316a is located near the head 312 and the second end 316b is located near the connection 320. The first end 316a of the intermediate portion 316 includes internal threads 352 configured to engage external threads 348 on the connector 336 of the head 312. The head 312 may thus be threaded into the intermediate portion 316. In alternative embodiments, the head 312 may be secured to the intermediate portion 316 by alternative mechanisms (e.g., fasteners, etc.). In some embodiments, the intermediate portion 316 and/or the head portion 312 may include a swivel joint to allow the head portion 312 to rotate or swivel relative to the intermediate portion 316. The second end 316b of the middle portion 316 includes a flange 356 (fig. 3D) located on an inner surface of the middle portion 316. More specifically, the flange 356 extends around the perimeter of the inner surface and secures the intermediate portion 316 to the connecting portion 320.

The connecting portion 320 extends from the second end 304b of the body 304. The connection portion 320 includes a conduit 360 defining an outlet 364, the outlet 364 being in fluid communication with the opening 324 and a wand or hose of the vacuum cleaner. The conduit 360 of the illustrated embodiment is generally cylindrical and includes a first end 360a adjacent the intermediate portion 316 and a second end 360b opposite the first end 360 a. Referring to fig. 3C and 3D, the conduit 360 includes a first shoulder 368, a second shoulder 372 having a smaller diameter than the first shoulder 368 and spaced inwardly from the first shoulder 368, and a groove 376 formed therebetween. Extending from conduit 360 are a first shoulder 368 and a second shoulder 372, second shoulder 372 being positioned on first end 360a of conduit 360. The groove 376 is shaped and dimensioned to receive the flange 356 on the intermediate portion 316. That is, when the intermediate portion 316 is coupled to the connecting portion 320, the flange 356 is positioned within the groove 376 and engages the first and

second shoulders

368, 372 to removably couple the intermediate portion 316 to the connecting portion 320. This connection between the flange 356 and the groove 376 of the intermediate portion 316 may thus be configured as a snap fit or a bayonet fit. The intermediate portion 316 and the connecting portion 320 may thus be coupled to each other such that they may rotate or swivel relative to each other.

Referring to fig. 3A-3E, the connection portion 320 additionally includes a universal coupler 380, the universal coupler 380 extending from the conduit 360 and configured to couple to vacuum hoses and rods having different sizes. The universal coupler 380 is substantially identical to the universal coupler 164 described above with respect to fig. 1A-1D. Reference is made herein to the above description of the universal coupler 164. In some embodiments, the connection 320 may include other configurations.

In some embodiments, the head 312 of the tool 300 has a width (measured between the widest points on the circumference of the head 332) of about 76.2 mm. In alternative embodiments, the tool 300 may have a smaller or larger width. The tool 300 additionally has a height (measured between the distal ends of the bristles 344 and the upper edge of the connecting portion 320) of about 92.5 mm. In alternative embodiments, the tool 300 may have a smaller or larger height.

In operation, the vacuum cleaner generates suction, which is applied through the connection 320 and draws dust and debris from the work surface into the inlet 328. The dust and debris is carried by the airflow generated by the suction of the vacuum cleaner to the outlet 364. The sharp edge 340 of the head 312 allows a user to position the tool 300 in a corner for cleaning. Scrubbing the working surface with the bristles 344 loosens dirt and debris caught on the working surface and helps clean the surface while also protecting the surface from damage. Bristles 344 on the sharp edge 340 of the head 312 allow the tool 300 to access dirt and debris located in narrow corners and seams.

Fig. 4A-4E illustrate an embodiment of a vacuum tool 400 configured to scrub a work surface clean.

The embodiment of the vacuum tool 400 shown in fig. 4A-4E includes a body 404, the body 404 having a first end 404A, a second end 404b opposite the first end 404A, and a longitudinal axis 408 (fig. 4C) extending between the first end 404A and the second end 404 b. Body 404 also includes a head portion 412, an intermediate portion 416, and a connecting portion 420. The head portion 412 is located near the first end 404a, the connecting portion 420 is located near the second end 404b, and the intermediate portion 416 is located between the head portion 412 and the connecting portion 420. The head portion 412 is integrally formed with the intermediate portion 416, and the intermediate portion 416 is integrally formed with the connecting portion 420. In other embodiments, the intermediate portion 416, and the connecting portion 420 may be formed as separate pieces that are assembled together as a single unit. The tool 400 also includes an opening 424 extending through the body 404 from the first end 404a to the second end 404 b. At least a portion of the opening 424 is parallel to the longitudinal axis 408.

The head 412 and the opening 424 define an inlet 428 for collecting dust and debris. The head 412 is generally cylindrical. In some embodiments, the head 412 may be configured in other shapes. The distal end 412a of the head 412 includes a groove 432 extending through a portion of the head 412. The grooves 432 are equally spaced around the circumference of the distal end 412a of the head 412. In the illustrated embodiment, the head 412 includes four grooves 432. However, in alternative embodiments, the head 412 may include fewer or more grooves 432.

Referring to fig. 4B and 4D, the tool 400 includes a brush member 436 coupled to the distal end 412a of the head 412. In the illustrated embodiment, the brush member 436 is formed in a shape similar to an "X". That is, the brush member 436 includes a first elongated support 440 integrally formed with a second elongated support 444. In the disclosed embodiment, the

elongated supports

440, 444 are generally rectangular and are oriented perpendicular to each other. In some embodiments, brush member 436 may be formed in other configurations. For example, in some embodiments, brush member 436 may form a shape similar to a "V". A series of several bristles 448 are coupled to the bottom surface 440a of the first elongated support 440 and the bottom surface 444a of the second elongated support 444. The bristles 448 are configured to selectively engage or otherwise be positioned adjacent a working surface for scrubbing the surface. Bristles 448 extend outwardly away from the

bottom surfaces

440a, 444a of the first and second

elongated supports

440, 444, respectively. Scrubbing with bristles 448 helps loosen dirt and debris from the work surface and protects the work surface from damage.

The distal ends of the first and second

elongated supports

440, 444 are positioned within the recess 432 on the head 412. The brush member 436 may be secured to the head 412 by any suitable fastening mechanism (e.g., fasteners, adhesives, etc.), and in some embodiments may be removably coupled to the head 412.

Referring to the embodiment shown in fig. 4A-4B, the intermediate portion 416 is cylindrical. In other embodiments, the intermediate portion 416 may be formed from other shapes and may be tapered. For example, the intermediate portion 416 shown in fig. 4E is cylindrical and has a larger diameter than the intermediate portion 416 of fig. 4A-4D.

Referring to fig. 4A-4C, the connecting portion 420 may be integrally formed with or otherwise coupled to the second end 404b of the body 404. For example, the connecting portion 420 may be coupled to the intermediate portion 416 by a rotary joint. The outer surface of the connecting portion 420 forms a gripping surface for a user to grip when operating. The connection portion 420 includes a conduit 452 defining an outlet 456, the outlet 456 being in fluid communication with the opening 424 (fig. 4C). When connected to a wand or hose of a vacuum cleaner, the outlet 456 is in fluid communication with the internal conduit of the wand or hose. The conduit 452 in the illustrated embodiment is cylindrical. In some embodiments, the conduit 452 may be formed of other shapes and sizes. For example, the catheter 452 shown in fig. 4E has a larger diameter than the catheter 452 of fig. 4A-4D.

Referring to fig. 4A-4C, the connection 420 further includes a universal coupler 460, the universal coupler 460 extending from the conduit 452 and configured to couple to vacuum hoses and rods having different sizes. The universal coupler 460 is substantially the same as the universal coupler 164 described above with respect to fig. 1A-1D. Reference is made herein to the above description of the universal coupler 164. In some embodiments, the connection 420 may be formed from other configurations.

In some embodiments, the head 412 of the tool 400 has a width (measured between the widest points on the circumference of the head) of about 71.0 mm. In alternative embodiments, the tool 400 may have a smaller or larger width. In addition, the tool 400 has a height (measured between the distal ends of the bristles 448 and the second end 404b of the body 404) of about 134.0 mm. In alternative embodiments, the tool 400 may have a smaller or larger height.

In operation, suction is generated by the vacuum cleaner and applied through the connection 420 to draw dust and debris from the work surface into the inlet 428. The dust and debris is carried by the airflow generated by the suction of the vacuum cleaner to the outlet 456. The user positions the tool 400 with the bristles 448 against a work surface. Scrubbing the working surface with the bristles 448 loosens dirt and debris that has built up on the working surface and helps clean the surface while also protecting the surface from damage. The X-shaped pattern of brush members 436 allows a user to effectively scrub a work surface in a horizontal "side-to-side" motion. More specifically, because the bristles 448 are closely positioned along the first and second

elongated supports

440, 444, the brush member 436 may be used to achieve enhanced scrubbing to effectively remove dirt and debris that has built up on a work surface.

Referring to fig. 5A-5F, another embodiment of a vacuum tool 500 is shown. The vacuum tool 500 includes a body 504, the body 504 having a first end 504a and a second end 504b opposite the first end 504 a. The body 504 also includes a base portion 512, an intermediate portion 516, and a connecting portion 520. The base portion 512 is located near the first end 504a, the connecting portion 520 is located near the second end 504b, and the intermediate portion 516 is located between the base portion 512 and the connecting portion 520. The base portion 512 is integrally formed with the intermediate portion 516, and the intermediate portion 516 is integrally formed with the connecting portion 520. In other embodiments, the base portion 512, the body portion 516, and the connecting portion 520 may be formed as separate components that are assembled together as a single unit. The tool 500 also includes an opening 524 extending through the body 504 from the first end 504a to the second end 504 b.

The base 512 and the opening 524 define an inlet 528 for collecting dust and debris. The base 512 includes a flange 532 that extends around the perimeter of the base 512. The flange 532 includes a first sloped portion 536a, a second sloped portion 536b, and a middle portion 536C of the base 512 (fig. 5C). The first and second

inclined portions

536a and 536b are located at both sides of the middle portion 536 c. Each of the first and second

inclined portions

536a and 536b is inclined with respect to the middle portion 536 c. In some embodiments, the middle portion 536c may be omitted and an angled or rounded portion may instead be located between the first and second

sloped portions

536a, 536 b.

The illustrated embodiment also includes a plurality of bristles 540 attached to the flange 532 adjacent the first end 504 a. Each of the plurality of bristles 540 extends away from the bottom of the flange 532, generally at a substantially right angle to the flange 532. As such, the bristles 540 attached to the first and second

inclined portions

536a, 536b are at an oblique angle relative to the bristles 540 connected to the middle portion 536 c. In the illustrated embodiment, each of the plurality of bristles 540 has a substantially identical length. However, other embodiments may include bristles 540 of different lengths.

The base 512 is in the shape of a generally truncated pyramid with rounded edges, with the top of the truncated pyramid connected to the middle portion 516. The shape of the base 512 allows and facilitates the transport of dust and debris to the intermediate portion 516 and then into the wand or hose of the cleaner. Base 512 includes a first wall 548a, a second wall 548b opposite first wall 548a, a third wall 548c, and a fourth wall 548d opposite third wall 548 c. Third and

fourth walls

548c and 548d extend between first and

second walls

548a and 548 b. The first wall 548a is connected to the flange 532 at the first inclined portion 536a of the base 512. The second wall 548b is connected to the flange 532 at the second inclined portion 536b of the base portion 512. The third wall 548c and the fourth wall 548d are each connected to the flange 532 at opposite ends of the middle portion 536c of the base 512. Base 512 also includes rounded corners at the intersection of each

wall

548a, 548b, 548c, 548d with the

adjacent wall

548a, 548b, 548c, 548 d. Other embodiments may include differently shaped bases 512, such as a truncated cone (frustoconical) or a truncated pyramid with rounded corners. In some embodiments, the flange 532 may be omitted and the plurality of bristles 540 may be directly connected to the end of each of the

walls

548a, 548b, 548c, 548d of the base 512.

The middle portion 516 is generally cylindrical in shape, although other shapes are also contemplated herein. The intermediate portion 516 transfers dirt and debris from the base portion 512 to the connecting portion 520. In some embodiments, the middle portion 516 may also serve as a handle for the vacuum tool 500.

The connecting portion 520 is integrally formed with the intermediate portion 516, but some embodiments may include the connecting portion 520 removably coupled to the intermediate portion 516 (e.g., via a rotary joint). The connection 520 is substantially the same as the connection 120 discussed above. Therefore, for simplicity, the connection part 520 will not be described in detail.

During operation of the vacuum tool 500, a user typically engages the working surface S1 with at least some of the plurality of bristles 540. As shown in fig. 5C, if the user engages the working surface S1 with bristles 540 extending from the middle portion 536C, there is a forward gap C1 between the working surface S1 and the bristles 540 extending from the first inclined portion 536 a. Likewise, there is a rearward gap C2 between the working surface S1 and the bristles 540 extending from the second inclined portion 536 b. Thus, when the user moves the vacuum tool 500 in the forward direction, dust and debris may easily move through the forward gap C1 into the inlet 528 and through the opening 524, while when the user moves the vacuum tool 500 in the rearward direction, dust and debris may easily move through the rearward gap C2 into the inlet 528 and through the opening 524. Further, if the user selects to use the vacuum tool 500 in a rocking motion, each of the forward clearance C1 and the rearward clearance C2 may be increased. As shown in fig. 5D, the user can engage the working surface S1 with the bristles 540 extending from the second inclined portion 536b while pushing the vacuum tool 500 in a forward direction, which provides a greater forward gap C1 between the working surface S1 and the bristles 540 extending from the first inclined portion 536 a. As shown in fig. 5E, the user can also engage the working surface S1 with the bristles 540 extending from the first inclined portion 536a while pulling the vacuum tool 500 in a rearward direction, which provides a greater rearward gap C2 between the working surface S1 and the bristles 540 extending from the second inclined portion 536 b. This arrangement allows the bristles 540 to be used to scrub the work surface to break up or loosen dirt and debris that may adhere to the work surface S1, and also move the front, and by providing the gaps C1, C2 allows the vacuum tool 500 to pick up larger items that are typically too large to pass through the bristles 540.
